Of all knowledge, the wise and good seek mostly to know them... - William Shakespeare

"We know what we are, but not what we may be."

"This life, which had been the tomb of his virtue and of his honour, is but a walking shadow; a poor player, that struts and frets his hour upon the stage, and then is heard no more: it is a tale told by an idiot, full of sound and fury, signifying nothing."

"Knowing I lov'd my books, he furnish'd me From mine own library with volumes that I prize above my dukedom."

"Love is a smoke made with the fume of sighs."

"There's no art to find the mind's construction in the face."
